Cai Zhaohou's decision was indeed too reckless and unwise. King Chu Zhao had actually forgiven Cai Zhaohou, but Cai Zhaohou did not forgive the other party; Cai and Chu could have resumed normal relations, and Cai would have benefited enormously from it; But Cai Zhaohou's stupid behavior not only caused great damage to Cai, but also pushed himself into the abyss from which he could never recover.

In the spring of the fourth year of Lu Dinggong, the situation in Cai Guo developed in a more turbulent direction. Armed fights over land ownership occurred from time to time, and every blood debt was eventually recorded on the head of Cai Zhaohou, and the contradictions between the doctors and Cai Zhaohou were also intensifying, and some people were already secretly planning a coup d'état and preparing to set up a new monarch.

Cai Zhaohou was anxious and overwhelmed by the huge threat. Gongsun Pian persuaded him to reconcile with the doctors, and even persuaded him to consider moving the capital back to its original location again, but Cai Zhaohou resolutely refused. He said: "The people of Wu have avenged the widow, and the widow cannot be untrustworthy to the king of Wu. Gongsun Pian persuaded him to go to Wu to avoid the limelight, and said that if the situation deteriorated further, he would not return, and Cai Zhaohou agreed.

Early one morning, Cai Zhaohou and his cousins Gongsun surnamed and Gongsun Xu disguised themselves as civilians and drove out of the east gate of the state in a car.

Cai Tong gathered his colleagues together and informed them of the news that Cai Zhaohou had left the city. Gongzi Si's son, Gongsun Qi, clamored and said: "Does the prince feel that Cai Guo is not close enough to Wu Guo and wants to move Cai Guo to the edge of Taihu Lake?" I think it's possible, then the people of Chu State can only enter Wu State to attack our country, but our country will become a county of Wu State! ”

People were anxious and panicked, and Wen Zhikai shouted: "Instead of sitting back and watching this old tyrant toss around, it is better to do something big to save the country!" The doctors erupted in approval and rushed out to catch up with Cai Zhaohou.

Gongsun Pian had something to deal with, so he went out of the city half an hour later than Cai Zhaohou. As soon as the chasing convoy left the city gate, someone spotted Gongsun Pian's chariot galloping in the distance.

Gongsun Qi pointed at Gongsun Pian and shouted, "Follow that villain to find the tyrant!" The crowd quickly chased after them, getting closer and closer to the goal. Gongsun Pian was so frightened that he kept shooting arrows to keep the enemy from approaching. The pursuers immediately discovered a serious problem: they were still wearing robes and ceremonial crowns because they had set out in such a hurry, that they did not look like they had come to fight at all; To make matters worse, they only had a bow and a pitiful few arrows.

The pursuers had to wait for their time from a distance. An hour later, the pursuers saw Cai Zhaohou's car. Several cars suddenly rushed towards Gongsun Pian, their purpose was to attract Gongsun Pian's attention and cover Gongsun Qi's attack. Gongsun Qi surrounded Gongsun Pian from the outside and went straight to the Marquis of Jin Zhao. He bent his bow and shot several arrows at Cai Zhaohou, Cai Zhaohou was hit by two arrows in the chest and abdomen, and fell to the ground, seeing that there was no help.

Gongsun surnamed and Gongsun Xujia broke into a farmhouse in front of Cai Zhaohou on the left and right, and as soon as the two put Cai Zhaohou down, he lost his breath. Gongsun Pian was furious, he opened his bow left and right, and his targets fell to the ground with arrows; He fought his way out of the crowd and stood proudly in front of the farmhouse. Gongsun's bow was too uncompetitive, and the bow was broken at the critical moment. Gongsun Pian had an arrow on his bow to intimidate the enemy, and there was only one arrow left in his quiver. But the pursuers were not ready to die with each other, they looked at Gongsun Pian from afar, and no one dared to take the lead in attacking.

Just when the two sides were at a stalemate, Wen Zhikai arrived. It turned out that he was worried about the lack of weapons, so he went home and got a pair of bows and arrows, and then rushed to the scene.

Seeing this, Wen Zhikai shouted: "What are you afraid of! We'll line up, and he'll be able to kill two people at most! So saying, he marched in with his bow, and the people followed in a wall with swords in hand.

Gongsun Pian said angrily: "Kai! If you dare to attack the prince, I will accuse you before the Emperor of Heaven after I die! "Say that an arrow is shot over, and it is the elbow of the Chinese Zhikai. Wen Zhikai returned an arrow and immediately shot Gongsun Pian to death. Enraged people rushed into the farmhouse and chopped the two grandsons inside into pulp.

After that, Cai Ren established the crown prince of Cai Zhaohou as the king, and it was for Cai Chenghou. Cai Chenghou is in name only, and the monarchy is in the hands of his father-killing enemies.

The death of Marquis Cai Zhaohou postponed the date for the Chu state to attack the state. After receiving the news that Cai Zhaohou was killed, King Chu Zhao sighed: "Cai Shen (Cai Zhaohou's name), you just live, you really don't want to make Bugu feel better!" ”

The Chu people thought that after the death of the Marquis of Cai Zhao, the Cai people would send an envoy to repair the terrible diplomatic relations between the two countries, but the Cai people, considering the actual situation of the country, thought that it was better to maintain the status quo (because the actual danger posed by Wu might be much greater than that brought by Chu), so they did not send an envoy to Chu. As a result, the Cai people's "stubbornness" angered the Chu people again.

During the outbreak of the war between Wu and Chu, Yihu (a branch of Huaiyi), which was entrenched in the area of Huainan in present-day Anhui, took advantage of the fire to rob the Chu State, and did not harm the local Chu people. After the war, the Yihu people were afraid of retaliation from the Chu State, and as a result, they stood more firmly on the side of the Wu people.

Starting from Yihu and crossing the Huaishui River to the north, it is the state. The Chu people were originally going to occupy the state first and then attack Yihu, but in order not to be covered with the notoriety of "taking advantage of the funeral to kill Cai", the Chu people changed their strategy and decided to take Yihu first, so as to observe the attitude of the Cai people.

In the summer and April, King Chu Zhao led his relatives to conquer Yihu. At that time, Zuo Sima Xuan commanded the Chinese army, Shen Gongshou Yu led the left army, and Ye Gongzi Gao (Shen Zhuliang, the son of Shen Yinxu) led the right army.

The Chu army went east out of Dabie Mountain. With the momentum of the wind sweeping away the fallen leaves, he quickly conquered Liu (now Lu'anbei, Anhui) and Chao (now Changfengnan, Anhui), and made preparations to attack the state. The Cai people were frightened by the majestic momentum of the Chu army, so the Cai army built a strong fortification on the north bank of the Huai River, and the Cai people asked for help from Wu, and Wu's reinforcements soon marched towards the state.

The Chu army had no plan to attack Zhoulai, so they traced the Huai River and took over the old land left by Cai in the west (in the area of present-day Xinyang, Henan). After that, the Chu army continued to march northwest, reaching fifty miles east of Liangcheng outside Fangcheng Mountain (near present-day Linru, Henan). Liang and the adjacent cities of Huo and Manshi were all cities established by Lu Hunrong, and the Manshi was still the capital of the Barbarian Kingdom.

Lu Hun Rong was originally a nomadic people, first entrenched in the border area of Gansu and Shaanxi, and later moved east to the narrow strip between Weishui and Qinling, facing the Qin State across the Weishui. When Qin Mugong and Jin Huigong expelled Lu Hurong to Yinchuan, Lu Hun Rong established a city-state following the Chinese way of life and began to live the life of an agrarian people.

However, they still retained the nomadic genes and ways of doing things in their bones, and as a result, they angered many countries by robbing passing caravans, including the state of Chu.

In the third year of Lu Xuangong (BC607), the Marshal of Chu Zhuang went north out of Fangcheng Mountain to attack Lu Hun, forcing Lu Hun to sign an alliance in the city, and Lu Hun became an ally of Chu. However, Jin Jinggong soon created a split incident in Lu Hun's country, separated the three cities of the barbarian clan from Lu Hun, and established the "Barbarian State". The Manshi and Lu Hun often fought with the support of Jin and Chu.

In the sixteenth year of Lu Zhaogong (BC526), there was a civil strife in the Barbarian clan; King Chuping ordered Ran Dan to trick the barbarian Zijia out and kill him, and then set up the son of the barbarian Zijia as the king, and the barbarian clan fell to the state of Chu. In the following year, the angry Jin people simply destroyed Lu Hun Rong as a sign of revenge against the Chu state; As a result, the Barbarian clan was greatly frightened and fell to the Jin Kingdom again. Later, due to the weakening of the Jin State Office, the Barbarian clan gradually gained a free body, so they didn't care much about the Jin Kingdom.

After the outbreak of the war between Wu and Chu, the barbarians thought that the opportunity for them to turn over and sing had come, so they set off a vigorous "anti-Chu movement". The barbarian forces swept away several Chu cities outside Fangcheng Mountain, killing the resisters, selling the captured population into slavery, and wantonly seizing land and property, causing great disasters to the Chu people.

The people of Chu hated the Barbarians even more than they hated the people of Wu—probably because they discriminated against Rong Di from the bottom of their hearts; King Chu Zhao had long vowed to erase the Barbarian clan from the Spring and Autumn Period, and it was for this purpose that he led a heavy army out of Fangcheng Mountain this time.
